chore(mythos): register dwarf.rs as Tier-5

[avrabe]

Adds meld-core/src/dwarf.rs to the Mythos auto-scan Tier-5 file list.

dwarf.rs holds the DWARF AddressRemap engine and the
DwarfHandling::Remap .debug_* rewrite (#143). A wrong remapped code
address silently de-grounds downstream coverage/breakpoints (LS-D-1), so
the file warrants the clean-room AI delta pass on every future diff.

Standalone workflow-only change: the claude-code-action identity check
requires the workflow file to be byte-identical to main, so this is
kept separate from the inc 3b code PR (#206) — same split as #197 for
provenance.rs.
